Length: 2.8 miles
Trailhead: Located directly behind the Logan Pass Visitor Center.
Start on the board walked trail, then continue the dirt trail to Hidden Pass. This is one of the best places to encounter mountain goats. Soon Hidden Lake Sperry Glacier basin come into view. The trail does continue just over a mile past the overlook and interpretive sign, but it is very steep down to the lake. (Note from time to time the trail and lake itself are closed due to Grizzly Bear activity. Be sure to get the latest trail status report before hiking.)
